Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998148, here are decompositions:

31 + 998117 = 998148
37 + 998111 = 998148
71 + 998077 = 998148
79 + 998069 = 998148
131 + 998017 = 998148
139 + 998009 = 998148
157 + 997991 = 998148
199 + 997949 = 998148

Showing the first eight; more decompositions exist.
